When once a sort of official, legal, or nominal Unselfishness has been established as a rule””a rule for the keeping of which their emotional resources have died away and their spiritual resources have not yet grown””the most delightful results follow. In discussing any joint action, it becomes obligatory that A should argue in favour of B’s supposed wishes and against his own, while B does the opposite. It is often impossible to find out either party’s real wishes; with luck, they end by doing something that neither wants, while each feels a glow of self-righteousness and harbours a secret claim to preferential treatment for the unselfishness shown and a secret grudge against the other for the ease with which the sacrifice has been accepted. Later on you can venture on what may be called the Generous Conflict Illusion. This game is best played with more than two players, in a family with grown-up children for example. Something quite trivial, like having tea in the garden, is proposed. One member takes care to make it quite clear (though not in so many words) that he would rather not but is, of course, prepared to do so out of “Unselfishness”. The others instantly withdraw their proposal, ostensibly through their “Unselfishness”, but really because they don’t want to be used as a sort of lay figure on which the first speaker practices petty altruisms. But he is not going to be done out of his debauch of Unselfishness either. He insists on doing “what the others want”. They insist on doing what he wants. Passions are roused. Soon someone is saying “Very well then, I won’t have any tea at all!”, and a real quarrel ensues with bitter resentment on both sides. You see how it is done? If each side had been frankly contending for its own real wish, they would all have kept within the bounds of reason and courtesy; but just because the contention is reversed and each side is fighting the other side’s battle, all the bitterness which really flows from thwarted self-righteousness and obstinacy and the accumulated grudges of the last ten years is concealed from them by the nominal or official “Unselfishness” of what they are doing or, at least, held to be excused by it. Each side is, indeed, quite alive to the cheap quality of the adversary’s Unselfishness and of the false position into which he is trying to force them; but each manages to feel blameless and ill-used itself, with no more dishonesty than comes natural to a human.
—The Screwtape Letters, Letter XXVI (emphasis mine), perhaps relevant to any of us planning family trips or vacations this summer
Back in 1942 when C. S. Lewis published [b]The Screwtape Letters[/b], no one was using the 12 Step language of “[i]co-dependency[/i],” Rabbi Edwin Friedman’s concept of “[i]self-differentiation[/i],” or similar jargon, but Lewis clearly understood the problem itself quite well. His masterful depiction of the psychological dynamics of temptation in that book has stood the test of time very well.
